    Abstract: A membrane actuator includes a magnetically actuatable membrane and a magnetic trigger. The membrane includes a shape memory alloy (SMA), and the magnetic trigger is configured to induce a martensitic transformation in the SMA, to produce a larger force than would be achievable with non-SMA-based materials. Such a membrane actuator can be beneficially incorporated into a wide variety of devices, including fluid pumps, shock absorbing systems, and synthetic jet producing devices for use in an aircraft. The membrane/diaphragm can be formed from a ferromagnetic SMA, or a ferromagnetic material can be coupled with an SMA such that the SMA and the ferromagnetic material move together. A hybrid magnetic trigger, including a permanent magnet and an electromagnet, is preferably used for the magnetic trigger, as hybrid magnetic triggers are easy to control, and produce larger magnetic gradients than permanent magnets or electromagnets alone.

    Abstract: Multiple embodiments of ferromagnetic shape memory alloy (FSMA) based torque actuators are described. These torque actuators include a magnetic trigger and an FSMA member, which when actuated by the magnetic trigger, produces a torque for rotating a member. Examples of magnetic triggers include hybrid magnetic triggers having at least one electromagnet and at least one permanent magnet. The FSMA member can be configured as a coil (or plate) spring and can be fabricated of a true FSMA alloy (i.e., an alloy that exhibits both ferromagnetic and shape memory properties) or of an FSMA composite that includes a ferromagnetic portion and an SMA portion. Several embodiments include a central orifice in which the FSMA member and an axial rod configured to rotate when actuated are disposed; the magnetic trigger system is disposed about the periphery of the orifice.

    Abstract: The present invention relates to an aluminum alloy having low density and enhanced heat resistance. An aluminum alloy having improved high temperature physical properties comprises: magnesium (Mg) in an amount of about 7 to about 11 wt %, silicon (Si) in an amount of about 4 to about 8 wt %, copper (Cu) in an amount of about 0.5 to about 2 wt % and manganese (Mn) in an amount of about 0.3 to about 0.7 wt %, and a balance of aluminum based on the total weight of the aluminum alloy. Vehicle parts such as a piston, a housing and/or a bed plate of high power engine, to which the aluminum alloy may be applied, are provided as well.
